ICS954147BFLF

Overview

The ICS954147BFLF is a timing controller IC designed for Intel CPU and PCI Express (PCIe) applications. Manufactured by Renesas Electronics Corporation, this component operates on a single 3.3V supply voltage and provides one clock output circuit. It is housed in a 56-SSOP surface-mount package with dimensions of 0.295 inches (7.50mm) width. The device functions within an operating temperature range of 0°C to 70°C. As indicated by the LF suffix, it adheres to lead-free manufacturing standards.

Feature Summary

• Designed specifically for Intel CPU and PCI Express (PCIe) system timing requirements
• Single circuit configuration providing dedicated clock output signals
• Operates at a standard 3.3V supply voltage
• Available in a 56-BSSOP surface-mount package for compact integration

Applications

• Intel-based computer motherboard systems
• PCI Express interface timing synchronization
• Server and workstation platform clock distribution

Procurement Notes

Verify the specific frequency specifications against the official datasheet, as the provided parameter list does not specify the maximum operating frequency. Confirm that the 56-SSOP package footprint matches the target PCB design constraints. Ensure the 0°C to 70°C commercial temperature range meets the environmental requirements of the intended deployment scenario.

Selection Notes

Select this component when a dedicated timing controller for Intel CPU and PCIe architectures is required. The choice depends on the compatibility of the 56-pin SSOP package with the assembly process. Consider the 3.3V logic level compatibility with the host system components. Verify that the non-programmable nature of the circuit aligns with the fixed frequency needs of the design.

Part Context

This part belongs to the ICS9541xx series of timing controllers from Renesas. These devices are engineered to provide stable clock signals for high-speed digital interfaces. The ICS954147 variant specifically targets the synchronization needs of legacy Intel processor platforms and associated peripheral buses.

Replacement Considerations

Check for direct pin-to-pin replacements within the same ICS9541xx family or newer generations from Renesas. Ensure any substitute maintains the 56-SSOP form factor and 3.3V operation. Verify that the replacement supports the specific PCIe and Intel CPU timing protocols required by the application.
